So I'm looking to get a set of cams for my car before/during summer. I'm not sure what to look into and I've been trying to search the site but it won't let me do any searches, so what do you guys suggest for cams 272's? Its a gen 2 3SGTE its my "DD" but who "DD's" a 3S swapped Celica (I plan on actually picking up a DD so i can work on my celica). And with the cams, what type of supporting mods, if any, would you recommended.
A thank you in advance!

I am really interested about this as well. I'm going for cheaper i hope. I was told getting the i think st215 or 205 cams for our 185 would be a great HP gain for cheap. Was told you don't need to change anything. i think from what i saw would be like Stock 225hp185jdm And adding those cams would give use like 245hp? maybe?

272s are really big and overkill unless youre going in excess of 400hp, and even then, still a lot. You will have a lopey crappy idle and make crap for vacuum.

264s are a good cam. GSC 268s are a good cam. Hell even a 256 is a good cam depending.

With cams, cam gears are pretty much a must. And its fairly worthless to put cams in an otherwise stock setup. If you want cams, you should already have a turbo at least. A CT20b/CT27 minimum. Theres a lot of reading about cams, dyno plots, etc over on mr2oc.

So if I swap a CT20b/27 does it bolt up to the CT26 plumbing? And then I just tune it, it as in the car?

The "safe bet" for good cams is the HKS 264. 272's are too big unless you plan to run boost in the 30psi+ range IMHO. The GSC 268 is getting good results too, especially in the 350whp range. HKS 256's are what I have, but haven't run the engine yet since installing so I don't have results (never seen dynos with them either). And they are hard to find.

Definitely need cam gears to degree them properly. A dyno tune for adjustments is even better.

On the stock ECU you might struggle to dial them in well, but might be ok as long as you have a way of keeping an eye on A/F with a wideband if you plan on running more boost.

Also like Luni said, I'd say a turbo upgrade should come before cams.

Here's a good thread on cams: http://www.celicatech.com/forums/showthread.php?47873-Cam-Specs-v.-Official-CTech-Cam-Spec-Thread

Check the links I've posted in there too with the cam comparisons.

Thanks :) I'll cruise through it tomorrow!

You will need to order new shims or do the shimless bucket conversion as well. Better valve springs are a must with 264's and 272's. Best bang for the buck is KOracings Engle valave springs.

You will have to check the shim clearances, but you may not need to actually replace them. Valve springs, to me, are completely optional unless using the high lift versions of cams or raising the redline. My 2c.

Somewhere along the line of putting a larger cam in you're going to want to switch to the shimless buckets so you don't spit a shim out.
I have no clue if either the 256 or the 264 has a high enough ramp to need that, it may not be until you go larger, but eventually it will need to be done.

^256 no, 264 low lift no, 264 high lift yes. Or if you raise the redline. :)

you don't have to go shimless. you can also go shim under bucket.
